Night of 31 August – 1 September 2026
4 objects · 3 h 43 min of light · 21:40–04:40 · Moon 85%
The telescope worked from 21:40 to 04:40 and shot Moon, Open cluster M103, Double Cluster in Perseus (h Persei) and Crab Nebula, gathering 3 h 43 min of deep-sky light.
The Moon was a waning gibbous at 85% illumination, a noticeable glow for broadband targets.
What was shot
| Time | Object | Filter | Exposure × frames | Stacked | Light |
|---|---|---|---|---|---|
| 21:40–21:41 | Moon | none | 6.25 ms × 20 | 20 / 20 | – |
| 00:11–00:31 | Open cluster M103 | none | 30 s × 29 | 29 / 29 | 15 min |
| 00:33–01:20 | Double Cluster in Perseus (h Persei) | none | 30 s × 77 | 77 / 77 | 39 min |

What worked and what got in the way
- First night on Open cluster M103.
- First night on Double Cluster in Perseus (h Persei).
- The longest night for Double Cluster in Perseus (h Persei): 39 min of light.
- A bright Moon (85%) lit up the sky, which hurts broadband targets most; the dual-band filter copes better.
